WILLIAM 0. ISAACSON, OF CHICAGO, ILLINOIS.

This invention relates to anchors for fastening bucks and the like intoplace and with regard to certain more specific features, to means forfastening construction members to masonry.

Among' the several obj ects of the invention may be noted theprovisionof a one-piece anchor for fastening wooden or like members to masonryand the like, said anchor being adapted to be accommodated to variouswidths of the wooden members; the provision of an anchor of the classdescribed adapted to be applied to various types of masonry; theprovision of an anchor adapted to be stamped from strips of sheetmaterial with substantially no waste; the provision of an anchor of theclass described which is rigid in its application, yet which is adapt-edto be easily applied because of its iiexibility before application; andthe pro visionkof a device of the class described which is economical ofmanufacture. Other objects will be in part obvious and in part pointedout hereinafter.

The invention accordingly comprises the elements and combination ofelements, features of construction, and arrangements of parts which willbe exemplified in the Struc-r ture hereinafter described, and the scopeof the application of which will be indicated in the following claims.

In the accompanying drawings, in'which is illustrated one of variouspossible embodiments of the invention,

Fig. 1 is a plan View of the anchor applied to one form of masonry;

Fig. 2 is a side elevation of Fig. 1;

Fig. 3 is a vplan view showing the manner in which the anchors are cutfrom a strip of sheet material; and

Fig. 4 is a planview showing a modified application of the anchor toanother form of the masonry.

Corresponding reference characters indicate corresponding partsthroughout the several views of the drawings.

Referring now more particularly to Fig. 1, there is illustrated atnumeral 1 a pair of legs joined together by means of a bendable or hingeportion 3. The hinge port-ion 3 is formed substantially at right anglesto the legs 1 and is formed as a pointed spur (see alsoFig. 3). Theexact shape is immaterial, except thatthe spur should be adapted to bedriven into a more or less chalky material such as gypsum. The legs 1are stiffened by ANCHOR.

suitable ridge portions 5 bentinto the material thereof. f

At the forward end of each of the pair of legs 1 is formed an extensionarm 7 which in the application of the anchor, is positionedsubstantially at right angles to the plane of the said legs 1. The arms7 are provided with suitable holes or openings for driving fastenerstherethrough, such as nails 9 adapted to be driven into the buck 11 orthe like. Screws or other devices may be used as fasteners.

The application of the anchor is evident from Fig. 1. The masonry member13 into which the anchor is driven by means of the spur 3 is composed ofa chalky substance such as pyrolite or the like. Before application, thelegs 1 of the anchor are parallel and `juxtaposed and the arms 7 are notbent angularly. Application is made by pulling the legs 1 apart, inscissor fashion until the arms 7 are properly positioned forv theparticular thickness of wall to whichthe anchor is being applied. Thespur is thus bent and automatically stiffened. The anchor is thenpositioned longitudinallyr along the wall until the arms 7 are properlypositioned for bending around the buck 11. At this stage the spur 3 isdriven down into the chalky substance by means of'a. hammer or liketool. The ends of the arms 7 are then conformed to the shape of the buck11 and the fasteners 9 driven home. The construction is then ready forthe application of the next member 13, the requisite plaster beingplaced over the anchor itself.

The' manufacturing operations required for making the anchor areillustrated in Fig. 3. A strip ofmaterial of proper'width is `fedthrough a punch press which outlines and cuts the shape of the anchor ina single flat sheet. The holes 8 for inserting the nails 9 may or maynot be punched at the same blow. A recess 15 is cut, separating thelegs 1. It may be seen from Fig. l3, that the shapes of the successiveanchors are nested, whereby material is conserved.

After the `outline of the anchor is cut, the holes 8 may be punched, ifthey have not already been punched when the outline was first formed.Crimps 17 are next put in for the purpose of permitting easy shaping ofthe anchor in the field or elsewhere. At this stage the ridge portions 5are also put in along the lines 19.

It is evident that the anchor mayr be lli) shipped fiat or shipped withthe proper bending operations having been performed at the crimped lines17. The anchorsare always shipped with the ridge portions il formedtherein, whether they are flat or bent into shape. i

Fig. 4 shows the application of the anchor to a hollow tileconstruction, wherein the spur 3 cannot be driven directly into the hardvitrilied material comprising the tile. In this case the anchor is bentas hereinbefore described, but the spur 3 takes up a position within oneof the recesses of 'the tile instead of being driven into the A ridge 23automatically formed therein, which ridge stiffens the spur 3 for thedriving' operation to be performed thereon 1n applying lthe member tothe masonry member 13.

Another advantage of the invention comprises the fact that after theanchor has been applied, the legs 5 are in a slanting position withrespect to the wall and hence act as struts to prevent movement of thebuck at right angles to the wall. Hence the bracing effect of thisanchor is much greater than that of most anchors.

In view of the above, it will be seen that thek several objects of theinvention are achieved and other advantageous results attained.

Asmany changes could be made in carrying out the above constructionswithout departing from the scope of the invention. it .is intended thatall matter contained in the above description or shown in theaccompanying drawings shall be interpreted as illustrative and not in alimiting sense.

I claim:

l. An anchor comprising a pair of legs joined by means of abend.able,portion substantially at right angles thereto, said bendableportion forming a spur and extension arms associated with said legsadapted to be joined to a member to be fastened.

2. An anchor comprising a pair of legs formed substantially in ahorizontal plane and joined by means of a bendable portion substantiallyat right angles thereto. said bendable portion forming a spur adapted.to be driven into masonry and extension arms associated with said legs,said arms and legs being adapted to be manually spread for accommodationto any thickness of wall,

whereby said spur is put into condition to be driven.

3. An anchor comprising a pair of legs formed substantially in ahorizontal plane and joined by means of a bendable portion substantiallyat right .angles thereto, said bendable portion forming a spur adaptedto be driven into masonry, and extension arms associated with said legs,said arms and legs being adapted to bemmanually spread for accommodationto any thickness of wall, whereby said spur is put into condition to bedriven. said arms being formed substantially at right angles to saidlegs. p

4. An anchor comprising a pair of legs formed substantially in ahorizontal plane and joined by means of a bendable portion at rightangles thereto, said bendable portion forming a spur adapted to beydriven into masonry and extension arms associated with said legs, saidarms and legs being adapted to manually spread for accommodation to anythickness of wall, whereby said spur is put into condition to be driven,said arms being formed substantially at right angles to said legs andadapted to be applied to a member which is to be held.
